Genetic diversity of Matrinxã breeding stocks: implications for management and conservation
Semina: Ciências Agrárias, 2021 The formation of fish breeding stocks for fish farming or conservation programs is commonly carried out from the capture of fish in natural environments. Information on the geographic and genetic origin of these stocks is important to guide actions that allow correct management in captivity and, when lost, harm production and genetic conservation.

β-Glucan-induced cortisol levels improve the early immune response in matrinxã ( Brycon amazonicus ) [PDF]
Fish & Shellfish Immunology, 2016 This study investigated the role of endogenous cortisol on the innate immune response in matrinxã (Brycon amazonicus) fed with β-glucan, prior to and after stressor exposure and bacterial challenge. For this, we evaluated the serum cortisol and plasma glucose levels, the serum lysozyme levels, the hemolytic activity of the complement system, and the ...

Anthropogenic Barriers Limit Fish Access to Essential Habitats in the Amazon in the Face of Climate Change. [PDF]
Glob Chang BiolRivers across the Amazon Basin are increasingly threatened by climate change and dam construction, which restrict fish movements. We combined climate projections with river‐network connectivity analyses to identify where suitable habitats for frugivorous and socioeconomically important fish are likely to persist and where access may be lost due to ...
